P52 - bluetooth connection loss

Hi guys,

 

I work on my P52 via bluetooth keyboard and mouse, periodically some problem occurs and they stop working at the same time.

 

Restore functionality is possible only by turning off and turning on the bluetooth on the laptop.

 

During failure, it is impossible to connect a new device.

 

I read the thoughts of one guy, he said that this is possible due to the overlapping of radio frequencies of Wi-Fi and Bluetooth.

Re: P52 - bluetooth connection loss

It feels like no one is using a bluetooth mouse...

Not experienced same problem as you.

 

But assuming that you run w10 1809, try this one (seems quite stable):

Hi abax,

 

Thanks for the link, I have already updated the bluetooth and Wi-Fi together with the complete removal of the driver.

 

Do you have a bluetooth mouse too?

 

I still have problems that did not fix after the update:

1. When I turn on the airpods in the hands-free mode and say something or turn on the music.

2. When I copy something or download torrents  on USB 3 external hard drive.

 

It feels like there is not enough bandwidth or Intel has poorly implemented balancing on the bus, there is no such behavior on Qualcomm.

Re: P52 - bluetooth connection loss

Hi Sergei,

 

sorry i cannot be of further help, as I do not have same symptoms as you.

I do use a bluetooth Logitech mouse (sometimes) and almost always a bluetooth Samsung speaker: but i have not seen any problems or disconnections.

 

Maybe someone using same devices as you, can be of more help.

 

PS: have tou tried to change your wifi connection into 5GHz, just to make sure it is not interference problem?

Re: P52 - bluetooth connection loss

abax,

 

I have three different problemstwo of them in theory you can reproduce and they are not related to interference.

 

1. If there is a microphone on your speaker, so there is a hands-free mode, just select the Samsung hands-free device and start playing music.

2. If you have an external hard drive and you can download something to it through a torrent, it is desirable to connect the drive to the port on the left side.

 

In both cases, the bluetooth mouse should start to lag as well as the ELAN touchpad.

 

My mouse - Logitech M555b.

Re: P52 - bluetooth connection loss

abax,

 

Unfortunately, problems are present even if the power adapter is disconnected from the laptop and I don't have a docking station.

 

It would be great if someone could reproduce my problems.
